“…The possibility of producing different types of nanofiber wires, able of a magnetically induced giant relative deformation, is very promising in view of their functionalization in those conditions where the filiform structure can lead to advantages. In fact, on the basis of recent bibliography, MENWs development seems to open renewals and finalizations for biomedical applications [43][44][45][46], sensing devices [47][48][49][50], electromagnetic components [51,52], absorbers [53,54], tissue engineering [7,55,56] and, in particular, to biocompatible components sensitive to external stimuli in order to regenerate or to activate the contraction and dilatation of tendons and muscles that have lost their functionality [57][58][59][60][61].…”

Magnetic field assisted electrospinning is supplemented by conductive sheets that envelop the magnets and have the same potential as the deposition electrode. By optimizing the experimental conditions, it is possible to produce wires made of polymer nanofibers that incorporate longitudinally oriented magnetic particles. The morphological and magnetic characterizations confirm the preferential orientations. The new nanofiber wires are easily aligned along the maximum intensity line of the applied magnetic field. Moreover, the nanostructured wires have high longitudinal elastomagnetic strain and high transversal deflection as a response to magnetic field stimuli. Therefore, these new threadlike aggregates of magnetic nanofibers could be very appealing for application in all microelectronic or biomedical devices whose functionality requires orientation or deformation.

The rapid development and popularization of smart and portable electronic devices have led to increasingly related electromagnetic pollution affecting human health and equipment safety. Thus, designing high‐performance electromagnetic interference (EMI) shielding materials with lightweight, flexible, and easy preparation is urgent. The intrinsic physiochemical properties of electrospun micro/nanofibers provide an attractive potential to ease and accelerate the next‐generation EMI shielding materials. Here, a detailed review of the electrospun EMI shielding materials is established. First, this article outlines the shielding mechanism of EMI shielding materials obtained via electrospinning. Then, the affecting factors of electrospinning process conditions on the resulting EMI shielding micro/nanofibers are discussed. Next, diverse fillers that contribute to the EMI shielding efficiency of electrospun materials are demonstrated. Finally, the conclusion and prospects are introduced, hopefully contributing to assisting with more comprehensive and rational designs of high‐performance electrospun fiber‐based EMI shielding for various applications. Priority measures and future directions are suggested for the future development of electrospun EMI shielding materials.

“…MNMs consist of either elemental magnetic materials such as iron, cobalt, and nickel or their oxides and mixed oxides. Among magnetic iron oxide nanoparticles, magnetite (Fe 3 O 4 ) and maghemite (γ-Fe 2 O 3 ) have attracted the most attention from various fields with regards to their applicability as drug delivery vehicles, − MRI contrast agents, ,, catalysts, − sensors, − and sorbents. ,− MNMs play a key role in immunoassays because these nanoparticles can be surface-modified with antibodies, oligonucleotides, and aptamers to enable selective binding to target viruses or their biomarkers . Functionalized MNMs can be applied in both the separation and detection steps of the immunomagnetic assay process.…”

Magnetic nanomaterials (MNMs) have gained great interest from different fields of study ranging from wastewater treatment to (bio)sensor development, taking advantage of both nanoscale size (allowing high surface-to-volume ratios) and the opportunity for magnetic manipulation. These materials can be surface-modified with antibodies, oligonucleotides, and aptamers to enable selective binding with target viruses or their biomarkers in biological samples. Using an external magnetic field, MNM-virus/biomarker complexes can be effectively isolated for further analysis. In some cases, the role of MNMs is not limited to simply serve as magnetic sorbents for extraction purposes as they have become an active part of some emerging detection processes (e.g., the use of magnetoresistive sensors). The combined application of MNMs with microfluidics for virus detection provides promising avenues for diagnostic tests that are of lower cost, require less time, and have higher specificity and sensitivity over conventional tests. This review focuses on the different approaches of virus detection using MNMs integrated in microfluidic chips. We will discuss recent research findings and provide insights and future perspectives for the development of low-cost and effective COVID-19 diagnostics tests.
